Definitions

  • the invention relates to a vacuum jug according to the preamble of claim 1.
  • the sealing element which is usually formed by a sealing washer or a sealing ring, is arranged on the underside of the sealing plug, and it interacts with it Because of the recess together, which surrounds the existing opening of the vacuum jug (DE-OS 2 548 199, DE-OS 3 342 356, DE-OS 3 433 354).
  • sealing bypass pouring channel is arranged in the sealing plug, which can be closed by a sealing member by a sealing mechanism extending through the sealing plug.
  • sealing problems can arise from the fact that, on the one hand, the sealing surface itself is not flat and, on the other hand, different starting and end positions for the seal or the sealing surface result due to the possible addition of dimensional deviations, as a result of which the sealing is impaired.
  • the problem is production-related and depends on the material of the parts of the vacuum jug, and it also arises with plastic vacuum jugs.
  • elastic, that is, compressible sealing elements have been provided which, although they allow tolerance compensation, are disadvantageous for technical reasons because the compression of the sealing element is associated with a significant expenditure of force.
  • the relatively high effort leads to increased wear, which reduces the life of the seal.
  • the invention is based on the object of designing an insulating jug of the type described at the outset in such a way that a secure seal is achieved even when relatively large dimensional deviations of the sealing parts are present.
  • the elastic seal is not compressed, but instead a bending tension is exerted on the sealing lips, under which the sealing lips bend.
  • the bending strength of the sealing lips is larger than the compressive forces exerted by the liquid absorbed in the can on the sealing lips.
  • the seal is ensured with a user-friendly operation of the sealing plug, because it is only necessary to apply the bending pretension which is lower than the tension required for compressing the sealing element in the prior art when closing.
  • the configuration according to the invention enables great flexibility of the sealing lips, as a result of which large dimensional tolerances can also be compensated for without the bending stress being significantly increased. The latter is made possible by the space between the sealing lips into which the sealing lips can bend.
  • the configuration according to the invention results in the desired seal even when the closed position is exactly maintained.
  • dimensional deviations are particularly noticeable as incorrect positions of the screw plug in the known configuration.
  • the design according to claim 3 enables easy assembly and disassembly of the sealing element.
  • the sealing towards the sealing plug is carried out automatically by the bending or reaction force which acts on the sealing element as a whole.
  • the vacuum jug generally designated 1 in Fig. 1 consists of the housing 2, an insulating insert 3 accommodated therein and the screw plug 4, with which the filling opening 5 of the vacuum jug 1 can be closed.
  • the insulating insert 3 which is a double-walled, evacuated glass vessel, is clamped between a screw-in base part 6 and an inner shoulder 7 of the housing 2, a sealing ring 9 being arranged between the edge 8 of the insulating insert 3 and the shoulder 7.
  • the shoulder 7 surrounding the filling opening 5 forms the bottom of a round recess 11 on the top side in the housing 2, into which the screw plug 4 can be screwed due to an existing thread 12.
  • a cross-sectionally Y-shaped sealing element 13 in the form of a ring is arranged on the underside of the screw plug 4, the web 14 of the Y-shape forming radially inward and the two sealing lips 15, 16 with respect to the central axis (10) of the insulating jug 1 point radially outwards.
  • the sealing ring 13 is held with its web 14 in a circumferential groove 17 on the screw plug 4, wherein in the closed position of the screw plug 4 shown in FIG. 1, the sealing lip 15 facing the latter with a step surface 18 on the underside of the screw plug 4 and the sealing lip 16 facing away from the latter the top 19 of the shoulder 7 cooperates sealingly.
  • the sealing lip 16 is located at a distance from the upper side 19 of the shoulder 7, which is denoted by a in FIG. 1, so that an annular gap for pouring out with one piece extending from the side of the recess 11 molded on the housing pourer 21 is created.
  • FIG. 2 shows the cross-sectional shape of the sealing ring 19 in the closed position of the screw plug 4, while in FIG. 3 the cross-sectional shape of the relaxed sealing ring 13 is shown.
  • the space 23 or spacing between the sealing lips 15, 16 enables the sealing lips 15, 16 to bend in the direction of the other sealing lip.
  • the bending stress of each sealing lip is larger than the tension that the liquid present in the insulating insert 3 can exert on the sealing lip 16, whereby the sealing is ensured, no matter how far the sealing lip 16 or both sealing lips are bent.
  • the difference between the largest distance B and the smallest distance b between the sealing lips 15, 16, which can theoretically be 0, is denoted by c in FIG. 3.
  • the sealing ring 13 can be automatically adapted to relatively large dimensional differences without the sealing being impaired. Such dimensional differences can be based both on unevenness of the upper side 19 and on different distances c of the sealing lip 16 from reference edges of the housing with respect to the closed position of the screw plug 4, in which a marking 24 in the form of a round elevation is located on the side facing the handle 22 .
  • the configuration according to the invention enables easy handling because the sealing element does not have to be compressed, as is the case in the prior art.
  • Another advantage of the configuration according to the invention is that when a screw plug 4 is present, its closed position with respect to the housing can be predetermined without the seal being impaired in the case of customary dimensional differences. This is ensured due to the mobility of the sealing lips 15, 16.
  • the sealing ring 13 is made of plastic.
  • the housing 2 and the screw plug 4 are made of plastic.
